| The qualitative and quantitative losses caused by stored product insects are of great concern, and since there is only a few active ingredients available for their control it is very important to have a frequent insect resistance monitoring. The objective of this research is to evaluate combination of bioassays and molecular marker techniques to detect insecticide resistance in stored product beetles. The Coleoptera species used for the tests were Sitophilus oryzae (L.) (Curculionidae), Rhyzopertha dominica (F.) (Bostrichidae) and Oryzaephilus surinamensis (L.) (Silvanidae). For the bioassays it was used the impregnated filter paper technique, applying 1 mL of deltamethrin (K-Obiol 25 CE TM) using four concentrations and five replicates, including a... |
